| (54) | Apparatus for controlling starting clutch of vehicle having function of stopping engine idling |
| (57) In an apparatus for controlling a starting clutch of a vehicle having a function
of stopping engine idling so that an engine (1) is automatically stopped, the starting
clutch being provided in a transmission of the vehicle in series with a belt type
continuously variable transmission mechanism (5), a load is applied to the transmission
mechanism (5) before a rise in a side pressure of the drive pulley and the driven
pulley at the time of vehicle start-up from the state of engine stopping, resulting
in a slipping of the belt. To avoid such a slipping, at the time of vehicle start-up
from the state of engine stopping, the engaging force (PSCCM) of the starting clutch
(7) is prevented from increasing above the creeping force which gives rise to the
creeping of the vehicle until after a lapse of a predetermined time (YTM2). In the
course of increasing the engaging force of the starting clutch above the creeping
force, the speed of rise in the engaging force of the starting clutch is limited to
a relatively low speed until after the lapse of the predetermined time (YTM4). The
occurrence of belt slipping due to a delay in the increase in the pulley side-pressure
is thus prevented. |
